Mismanagement● Lt Gen Daniel Darnell estimated that USAF will be short of it 2250 fighters requirement by 800 aircraft in 2024● “fly before you buy” policy abandoned – bugs discovered and hastily patched up during production – or not patched up at all

7.
Effects of training● US commander in Gulf War: “Had we exchanged equipment with the enemy, result would have been same.”● In 70s and 80s, instructors in F5s whipped studensts who flew F14, F15 and F4

9.
Effects of numbers● Lanchester square criteria – Per-unit combat effectiveness of outnumbered side must be square of outnumbering sides numerical advantage just for outnumbered side to break even – In WW2, USAF had quantitative advantage; in both Gulf wars and in Operation Allied Force, USAF had both qualitative and quantitative edge

10.
F22s shortcomings● 26 % increase in weight lead to thrust-to-weight ratio and wing loading inferior to that of F15C; promised increase in manouverability not achieved● Fuel fraction decreased from 0,36 to 0,28 – insufficient persistence● Supersonic cruise ability worse than that of F15● Very large – very visible in visual, infrared and acoustic spectrum● Radar can be sensed by advanced RWRs – imprudent to rely on it as main battlefield sensor

11.
F22 shortcomings● No passive sensors that can detect non-radiating enemy fighter● Weapons held in bays / covered by doors due to stealth requrements – unable to perform quick shots

12.
Anti-stealth● UHF radars display continual increase in capacities● Long wavelength (VHF) radar can easily detect any stealth fighter due to their dimensions creating resonance; stealth coatings ineffective for reasons of physics● IRST – can detect fighters from distances of 50+ km; missile launch can be detected from 90 km● Passive radar – forces VLO fighter to rely on IRST or risk being detected by using its own radar

13.
Anti-stealth● LIDAR – Light Detection And Ranging – can detect particles from exhaust at distance of beyond 100 km● Background scanning – stealth fighter shows as a hole in data in front of background being scanned● Multistatic radar – emitter and receiver not in same place● Over-the-horizon radar
